The Banco de Buenos Ayres was established in 1822 under Bernardino Rivadavia's reformist government and became the first bank of issue in the Río de la Plata region. This note predates the catastrophic 1826 financial crisis that would force the bank's conversion into the Banco Nacional de las Provincias del Río de la Plata — meaning notes from this year sit right at the inflection point before the institution collapsed under the weight of war financing for the Cisplatine conflict against Brazil.

Printed locally in Buenos Aires, the note is among the earliest paper currency produced in Argentina rather than contracted to European printers.
